That must be awful. I suffered a perforated ear drum many years ago, and the doctor who treated me at the time had a hard time seeing the eardrum clearly, so he irrigated that ear, I was literally climbing up his arm, writhing in pain.
He prescribed darvasette (sp?) and for 24 hours I knocked myself out with them. Any pain that originates that close to the brain is really unbearable.
For Rush's sake only, I hope he didn't do anything that was contra the law. He is loved by a lot of people and hopefully that'll be enough to see him over this hurdle.
